Lifter profile Type This combo box lets you pick the type of lifter and the steepness or aggressiveness of the cam s profiles The combinations consist of Hyd vs Solid Hydraulic vs Solid lash adjustment Flat vs Roller Aggressiveness or steepness of the profile Roller being more aggressive Mild vs Agr Aggressiveness or steepness of the profile Agr being more aggressive The choice of Hydraulic vs Solid is the most important as this dictates the use of a lash setting The other choices simply determine differences in the steepness of the profile for the same Max Lobe Lift Most truly aggressive cams or roller cams have more Max Lobe Lift for a given duration and milder or hydraulic cams have less Max Lobe Lift For Cyl Click on the down arrow button to select the Cylinder for this particular cam lobe This is mainly used when you are measuring a cam lobe or reading a cam file Important The specs below may update change as you change other specs For example if you change a centerline the Total Cam Advance number changes to reflect the new centerline Rocker Arm Ratio Identifies the ratio between tappet lift and valve lift Generally rocker arm ratios vary between 1 3 to 2 0 For valve trains with no rocker arms for example overhead cam systems with directing acting tappets enter 1 See Figure 2 13 The Pro assumes the ratio is constant although actual rocker arm ratios vary slightly with valve lift

SSS a a ny Note If we were doing measurements every 10 degrees instead of every 5 degrees our measurements would not be as accurate Then we could only expect to be within say 3 4 degrees of the cam grinder s specs See Appendix 1 Table 4 1 compares the cam grinder s duration specs with those actually measured Since all Intake specs are within a couple degrees of our measurements we can assume that our measurements are good It also compares Exhaust specs and measurements however they have not yet been measured in this example Note Do not be surprised if cams are not ground exactly to the advertised specifications Production tolerances make it nearly impossible for cams to be ground exactly to spec at an affordable price Fortunately minor changes in cam duration and timing have a relatively small impact on engine performance However small bumps on cam profiles can produce abnormally high wear on valve train components Figure 4 18 Duration Report Click on Back to return Summary of Measured Cam Specs to Main Screen Save Measur e pA Can Analyzer v2 0 Performance Trends C48094 5 R04 D ata E Back Print Report Types File Help F1 l Report of Cam Data Test ime 10 40 am 03 13 2000 Events Rated at 050 Tappet Lift Since all our checks of the Comments int 1083 08 HE B2 403 HTH 16 DO OT ead Intake Lobe look good we Esh 360 0 0 180 0 360 0 00 OOO 000 16 O22 1283 ay majoreros mesiring ee eee a any major errors

18. Performance Trends Inc 2000 Cam Analyzer Chapter 4 Examples Appendix 1 Accuracy and Assumptions Accuracy The accuracy of the Cam Analyzer s cam measurements like Lobe Area Int Opening at 050 Duration 200 depend on 1 Accurately finding TDC and setting the degree wheel to TDC 2 Accurately setting the crank and cam to the Degree Wheel Readings points 3 Accurately recording tappet Cam Lift 4 The number of data points you record The more points the lower the Deg Steps the more accurate the results The following Tips for Accurate Measurements will help you with the first three requirements The section Effect of Deg Steps discusses the fourth point Tips for Accurate Measurements 1 Double check your measurements When finding TDC and you have found the 2 degree wheel points one on each side of TDC rotate the crank to these readings again and see if they repeat If you have just set the degree wheel and pointer to read TDC check that this agrees with your previous TDC or spark timing marks For example when your degree wheel and pointer are set to TDC do the timing marks on the damper also read TDC You may have to remove the degree wheel and install the damper temporarily to check this If they agree then the original marks and your degree wheel and pointer setting are most likely both correct If they do not agree repeat the procedure for finding TDC When you just finished recording the last Cam Li
19. Select the Method to Determine TDC the method you will use to determine piston position on either side of TDC either Method 1 uses a dial indicator to measure out 2 points on either side of TDC A disadvantage of Method 1 is that the heads must be removed or you need a special dial indicator which can access the piston dome through the spark plug hole Method 2 uses a mechanical stop in the cylinder or head A stop can be a stiff bar bolted to the engine deck as shown in Figure 2 17 on page 29 Or it can be a spark plug body with the porcelain removed and a bolt welded in its place This type can be used with the head installed but can bend introducing errors damage a piston with a complicated dome or not work at all depending on spark plug installation angle The stop will contact the piston at the same distance from TDC with the crank on either side of TDC Two disadvantages of Method 2 include e Possible damage to the piston if too much force is used to seat the piston against the stop e Depending on the design of stop you may have to remove and adjust or file the stop if the degree wheel readings do not fall into the range allowed by the Cam Analyzer 1 For this example we will use Method 1 so select the Dial Indicator method You will notice that as each step is answered the next step becomes enabled so you can answer it 2 Set Approximate TDC and Zero This step is to get the degree wheel in the ball park
